right. i am trying to build my first ever computer and already hitting problems as i am not sure of certain specs etc. i mainly surf the net burn dvd,s cd,s and would like to use this new computer as a media centre. i now and again play games but rarely and usually unreal 99. is crossfire sli only for gaming or would dual cards speed up the movie dvd burning process. anyway this is the spec i was thinking about. cooler master wave case, intel 6600 cpu, asus P5w dh delux motherboard, thermalite tough power 700w psu, thermalite ultra 120 cpu cooler, seagate 80gb and 500gb hard drives, 2 sony 18x dvd burners, creative sound blaster x-fi sound card. not sure which but 2gb ram and not sure but around the £200 mark for a graphics card. any explainations on crosssfire sli and this setup or why i should change certain items would be really welcome. thanks in advance Maxiboy
